Step-by-step explanation:
The centroid divides the length of each median in 2:1 ratio.
The length of the part between the vertex and the centroid is twice the length between the centroid and the mid-point of the opposite side.
When CD is the median, C is the vertex and D is the midpoint of AE.
CG = 2 × DG
6.5= 2(3x- 11)
6.5 = 6x -22
6x= 6.5+22
6x= 28.5
x= 28.5/6
x= 4.75
optionB
Answer:
Blue = y = -2x - 5 Red = y = -3x + 3
Step-by-step explanation:
Blue line
y = mx + b
y = y coordinate
m = slope (rise/run, up/over, change in y/change in x)
x = x coordinate
b = y intercept (where the line crosses the y-axis.
Blue Red
1. Write the equation y = mx + b y = mx + b
2. Substitute the numbers in the proper place. y = 2/1 x - 5 y = 3/1x + 3
3. Check for the type of slope- (positive or negative) y = -2x - 5 y = -3x + 3
(Downhill slopes are always negative.)
The correct answer would be to divide both side by 64 so (A)
Well 57+59+61= 177 so the answer is 57
Answer:
C. 3x+13
Step-by-step explanation:
Because
12x+52=
4(3x+13)
The 4 is the sides of a square
